[Desktop-packages] [Bug 1598993] Re: xrandr scaling corrupts external monitor output
I recently reproduced the same problem without using scaling, by connecting to a different external monitor. Now the problem exists in every video mode. Perhaps a problem of compatibility with Sky Lake integrated graphics in Thinkpad X260 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1598993 Title: xrandr scaling corrupts external monitor output Status in xorg-server package in Ubuntu: New Bug description: after doing xrandr --output HDMI2 --scale wxh, using any values except 1x1, the screen becomes increasingly distorted when typing in an editor window.

[Desktop-packages] [Bug 1598993] Re: xrandr scaling corrupts external monitor output
For any who are affected by this, here is a work-around. I was able to add a screen resolution that was detected for my internal monitor, but not for the external one, using xrandr --addmode. It gets the width of the screen right, but truncates the bottom. However panning makes the bottom accessible, so this is not a serious limitation. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1598993 Title: xrandr scaling corrupts external monitor output Status in xorg-server package in Ubuntu: New Bug description: after doing xrandr --output HDMI2 --scale wxh, using any values except 1x1, the screen becomes increasingly distorted when typing in an editor window.
